In a preferred embodiment, the groove surface is entirely wider at the top and narrower at the bottom, and the width of the narrowest side of the groove surface is the same as the width of the through hole at the lower side of the water inlet.
In a preferred embodiment, the bottom of the upper brick cup is provided with an integrally formed boss in a protruding mode, and the upper wall of the lower brick cup is provided with a groove in a concave mode, wherein the groove meets the insertion of the boss.
In a preferred embodiment, the concave-convex type primary-secondary port butt joint structure is formed by combining the grooves and the bosses between the upper seat brick and the lower seat brick.
In summary, due to the adoption of the technical scheme, the beneficial effects of the utility model are as follows:
1. in the utility model, the joint of the ladle upper nozzle and the upper pocket block and the joint of the upper and lower nozzle pocket blocks are staggered, and the joint of the ladle upper nozzle and the upper pocket block is higher than the joint of the upper and lower nozzle pocket blocks, so that the height difference of the joint is formed, and the possibility of steel seepage at the joint is greatly reduced by the design.
2. According to the utility model, the upper part of the through hole of the ladle upper nozzle is changed into a bell mouth shape, which is beneficial to the eccentric block of the drawing device to be clamped at the bell mouth position of the through hole, so that the ladle upper nozzle and the eccentric block of the drawing device are effectively stressed, and then the nozzle is pulled out through the pull rod, thereby improving the efficiency of replacing the upper nozzle.
3. In the utility model, the boss and the groove are respectively arranged on the upper pocket brick and the lower pocket brick, so that the installation precision of the upper pocket brick and the lower pocket brick can be improved, and meanwhile, the design is convenient to take out the upper water gap and the probability of steel seepage is reduced only by changing the overall shape and the overall size without increasing the cost.
